  ** * = can be optionally printed if nonzero
  ** .pp
  ** Some of the above sequences can be used to optionally print a string
  ** if their value is nonzero.  For example, you may only want to see the
  ** number of flagged messages if such messages exist, since zero is not
  ** particularly meaningful.  To optionally print a string based upon one
  ** of the above sequences, the following construct is used
  ** .pp
  **  %?<sequence_char>?<optional_string>?
  ** .pp
  ** where \fIsequence_char\fP is a character from the table above, and
  ** \fIoptional_string\fP is the string you would like printed if
  ** \fIstatus_char\fP is nonzero.  \fIoptional_string\fP \fBmay\fP contain
  ** other sequence as well as normal text, but you may \fBnot\fP nest
  ** optional strings.
  ** .pp
  ** Here is an example illustrating how to optionally print the number of
  ** new messages in a mailbox:
  ** %?n?%n new messages.?
  ** .pp
  ** Additionally you can switch between two strings, the first one, if a
  ** value is zero, the second one, if the value is nonzero, by using the
  ** following construct:
  ** %?<sequence_char>?<if_string>&<else_string>?
  ** .pp
  ** You can additionally force the result of any printf-like sequence to
  ** be lowercase by prefixing the sequence character with an underscore
  ** (_) sign.  For example, if you want to display the local hostname in
  ** lowercase, you would use:
  ** %_h
